Responding to app store server-server notification

We are utilizing the App Store's server-to-server notification feature. Upon receiving a notification on our server, is there a specific deadline or time limit for responding back to the App Store?

We just skimmed through the below documentation https://developer.apple.com/documentation/appstoreservernotifications/responding_to_app_store_server_notifications

In this doc we could only see the responses that app store is expecting us to send back but no any information regarding acknowledgment time for a request

Hello, thank you for reaching out. So when you receive the notification, your server then responds with an HTTP 200 status code. That is the response we are expecting there.

If your server doesn't reply in a timely manner, the connection will timeout and the App Store Server will consider the notification send unsuccessful. It will then enter the retry process. To avoid these unnecessary retries, we highly recommend the receiving process on your server simply record the notification and return 200. Then have an async process on your server take any actions associated with the notification, e.g. revoking content for REFUND notifications.
